Interesting. Don't capitals fulfil that function? Maybe a slight bonus from being on Coruscant?
Nonetheless, I keep wondering if different bonuses might be applied. There are already alot of discounts, credit increases etc, why not make buildings build faster instead (better bureaucracy sorting out the paper work and allocating labour faster)? What do you think?
I did a post on governmental policies that did decreased building time and other bonuses, so I might try and update that if it interests anyone.
